Sorry. I add this and kernel is builded now.

At the first boot I got a panic on a gif interface. I don't need it now so
I commented it out of rc.conf.local and reboot.

New kernel is running with WITNESS and INVARIANT... System seems not too loaded ...

I am at home and the serial console is not connected. I snapshot the KVM of the panic
and attatch it to this mail for the record.
